PATENT JOHN DAGGETT, OF ELYRIA, OHIO, ASS IGNOR OF ONE-HALF TO MORGAN H.LANDERS, OF ELYRIA, OHIO.

DEVICE FOR REINSULATING ELECTRIC AND AERIAL TELEPHONE OR OTHER CABLES;

SPECIFICATION forming part of Letters Patent No. 727,756, dated May 12,1903. Application filed November 14, 1902. Serial No. 13l,365. (Nmodel.)

To all whom it may concern:

Be it known that I, JOHN DAGGETT, a citizen of the United States,residing at Elyria, in the county of Lorain and State of Ohio, haveinvented a new and useful Device for Beinsulating Electric and AerialTelephone or other Gables, of which the following is a specification.

My invention relates to a device for rein- [o sulating telephone andother electric cables.

that are suspended in air and in which for some cause the originalinsulation has become im perfect and the cableimpregnated with wa-' terand from which the water needs to be ex- 15 pelled and the cable-strandsreinsulated without taking the cable down.

The object of my invention is to provide a port-able device that can besuspended underneath the cable at any desired point and admit of thewater being expelled from the cable, the strands of the cablereinsulated, and after any portion of the cable has been treated movedalong lengthwise of the cable, as may be desired. I accomplish theseobjects by 2 5 means of the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of my invention appliedto the messenger or supporting cable of a telephone or other cable.

or plan view of my invention, and Fig. 3 is a transverse sectional viewof Fig. 1 in thed0tted lines X X. Similar letters refer to similar partsthroughout the several views.

A represents the messenger or supporting cable by which thetelephone-cable issupported and to which my device is attached.

(1 represents the telephone-cable, which is supported by themessenger-cable and hangs underneath same.

B represents a narrow trough, preferably of metal, deeper in the centerthan at the ends and of any convenient width to receive thetelephone-cable and wider in the center to more readily absorb heat frombelow.

Near the center and underneath the trough B is attached a suitablereceptacle b for receiving and holding a lam p, gasolene-furnace, orother heating device. This recep- 5o tacle is closed on all sides, butprovided with doors or other devices on the sides, through Fig. 2 is atop which the lamp or other heating device may be introduced, and with aseries of small holes or other openings near the top for the escape ofthe products of combustion. Near the ends of the trough are attachedsupportin bars 0, to the outer ends of which are attached bifurcated orforked suspension-pieces c. The upper ends of these suspension-piecesare provided with a series of parallel holes. The forked ends of thesepieces 0 may be of any desired length and extend up on opposite sides ofthe telephone or other cable and the messenger-cable. Between the forkedends of the pieces a is placed a grooved pul- Icy-wheel 0, provided witha pin, which may be inserted through any of the series of holes in theends of the pieces 0 and said pulleywheel, and thereby support theentire device on said pulley-wheels-and messenger-cable. By means of theseries of holes in the pieces 0 the trough B can be held at any desireddistance below the messenger or supporting cable A.

The operation of my invention is as folthen placed in the trough in suchamount as may be necessary, paraffin-wax being the insulating materialmostgenerally used. Heat by means of a lamp or furnace is introduced inthe receptacle 5 and the heat therefrom communicated through the bottomof the trough to the insulating material in said trough and thencepermeating all through the strands of the cable therein, whereby allmoisture and water is driven off in vapor and the insulating materialpermeates and fills up all the space between the strands of said cable.Said cable is then removed and my device run along by the pulley-wheelsto any 5 other section or entirely detached, as may be desired.

Having fully described myinvention and its operations, what I claim asnew, and for which I desire to obtain Letters Patent of the [CO UnitedStates, is
